ABSTRACT:
A dental examination mirror is provided. The dental examination mirror includes an examination unit having a planar base wall and a side wall projecting upwardly and outwardly from the base wall. The side wall includes an edge remote from the base wall. A mirror wall is sealingly secured to the edge of the side wall and is substantially parallel to the base wall. The surface of the mirror wall facing away from the base wall are reflective to permit observation of regions in an intraoral cavity. At least portions of the mirror wall enable transmission of light. A light source and a heat source are disposed in the examination unit between the base wall and mirror wall. Light from the light source will be transmitted through at least portions of the mirror wall to illuminate at least portions of the intraoral cavity without shining light toward the eyes of the dentist or patient. The heat source in the examination unit prevents fogging of the mirror.
